It's rarely as blunt as this, though. Usually people who support such politics will insist that it is democratic, and they do have a point: what they really want is a democracy in which the majority (which includes themselves) gets to do whatever it wants to others.

I agree that you can't really legislate this kind of sentiment away, but I don't think attempts to do so are entirely useless, either - they slow down the process, which, at the very least, buys more time for potential targets to realize what is happening and get out of harm's way through emigration etc.
